Alpaca Partners With Kalshi to Bring Prediction Markets to Brokerage Infrastructure

Quick Summary

Alpaca has integrated with Kalshi to offer event contracts and prediction markets directly within its API-first brokerage infrastructure. This enables fintechs and financial institutions to provide trading on real-world events through a single integration alongside traditional asset classes.

How Does Alpaca Integrate Prediction Markets into Its Infrastructure?

Alpaca expands its API-first platform by partnering with Kalshi, allowing financial institutions to embed event contract trading directly into existing consumer applications. By using single API integrations, fintech developers avoid building separate technology stacks for specialized asset classes.

Through Alpaca Derivatives LLC—a CFTC-registered Futures Commission Merchant (FCM)—Alpaca manages core brokerage operational mechanics including custody and account management, while Kalshi supplies the underlying regulated marketplace, event contracts, and clearing mechanisms. Key metrics defining the scope of this partnership include:

• Over 300 financial institutions served by Alpaca's infrastructure.
• More than 10 million brokerage accounts supported across 40+ countries.
• $40 billion in trading volume processed by Kalshi in July alone.

What Are the Benefits of Prediction Markets for Retail and Institutional Platforms?

Integrating Kalshi event contracts gives platforms direct access to high-demand markets covering economic indicator forecasts, financial indexes, sports, weather, and geopolitical events. Investors can hedge positions or speculate on real-time event outcomes using the daily trading tools they already trust.

“Alpaca’s partners and users want to access more markets without having to build and manage a separate infrastructure stack for every asset class,” said Tony Lee, Chief Brokerage Officer at Alpaca.

“Partnering with Alpaca is a significant step in expanding access to Kalshi markets in the US and around the world,” said Max Crowley, VP of Business Development at Kalshi. “Alpaca powers a fast-growing ecosystem of financial platforms, and together we can bring prediction markets directly into the products investors already use to trade and manage their money.”

FF NEWS TAKE:

Embedding regulated event contracts into mainstream brokerage APIs marks a major maturation phase for event-based trading. Bringing prediction markets alongside equities and crypto legitimizes event contracts as standard portfolio tools, forcing legacy retail brokerages to evaluate whether single-asset trading interfaces remain competitive in an increasingly multi-asset retail environment.
